What aspects should be paid attention to in the maintenance of water-cooled plates and water-cooled units?
The normal operation of the water-cooled equipment affects the normal operation of the machine. In order to make the machine run more stably and increase its service life, the maintenance and maintenance of the aluminum cold plate of the water-cooled equipment has become a must.
A technician from the cold plate manufacturer told the editor that during normal operation of the liquid cold plate chiller, it is inevitable that dirt or other impurities will affect the cooling effect. Therefore, in order to prolong the service life of the water-cooled plate chiller and achieve the best cooling effect, regular maintenance and maintenance work should be done to ensure the operating quality of the chiller and improve production efficiency. So what should be the correct approach?
(1) Regularly check whether the voltage and current of the water cold plate chiller are stable, and whether the compressor's operating sound is normal. If it is a semi-hermetic compressor, check the oil quantity regularly. Normally, it should be more than 2/3 of the window. When the water-cooled plate chiller works normally, the voltage is 380V and the current is within the range of 11A-15A. It is normal. The normal use of electricity is the most basic guarantee.
(2) Regularly check whether the cold plate chiller refrigerant leaks: it can be judged by referring to the parameters displayed on the high and low pressure meter on the front panel of the host. According to the temperature (winter, summer) temperature changes, the pressure display of the chiller is also different. When the chiller is working normally, the high pressure display is usually 11-17kg, and the low pressure display 3.5kg-5kg is normal. If abnormal conditions occur, you need to Further determine the cause.
(3) Check whether the cooling water system of the water-cooled plate chiller is normal, whether the cooling tower fan and sprinkler shaft are running well, and whether the water supply of the built-in water tank of the water-cooled plate chiller is normal. The water-cooled plate chiller should be replaced with new water once every three months. If it cannot be replaced, please add a descaling agent to ensure the smoothness of the water-cooled plate.
(4) All industrial chillers should be cleaned when they are used for six months. After that, they must be cleaned once a year. The main cleaning parts include: cooling water towers, radiator pipes and condensers to ensure better cooling effect. Cleaning at the same time It is also the point in time to check for abnormalities.
(5) When the water-cooled plate chiller is not used for a long time, the circuit switches such as the water pump, compressor and the main power supply of the cooling water tower should be turned off in time, and the start operation should be performed when it is needed again. The water-cooled plate chiller needs to be connected with a cooling water tower and a circulating water pump to achieve the cooling effect. In order to ensure the quality of the circulating water, you can consider installing a Y-type filter at the water source and adding algicide and descaling agent to the cooling water tower to avoid impurities Into the pipeline or cause algaeification of water and affect the operation of the unit.
(6) The water-cooled plate chiller uses the designated refrigerant. If you want to replace it, you need to find the original factory to know the model of the refrigerant, and then purchase and replace it. If the fault occurs, please check the system according to the fault indicator. If the fault cannot be eliminated, do not disassemble the machine without authorization, especially in unprofessional situations. At this time, contact the original after-sales service of the water-cooled plate and request technical support.
Good use habits and maintenance methods can better ensure the operation of the machine, and at the same time greatly increase the service life of the machine, which brings great hidden benefits.
